Sense of responsibility
Under normal circumstances, where parents are responsible for looking after their kids. It takes time for kids to take up their own responsibility once they start getting mature. With pets around, kids tend to learn to handle responsibility earlier and better. Also because parents rely on kids when it comes to looking after pets more than with their younger siblings.
Give and Take
Parents tend to love their children irrespective of what they receive in return. This sense of security doesn’t help them in learning the idea of give and take in love. Whereas when kids are around pets they initiate love and in return they receive this exchange of gestures teaches them this minor but very effective lesson of give and take in love.
Think before you hit someone
The younger siblings are mostly not able to fight the older ones till certain age. This gives them the dangerous confidence of hitting without thinking about immediate consequences. While with cats and dogs they learn that every action has its equal or more than equal opposite reaction. So every time they are about to hurt they think about the instant result and hold back their emotions.
Love for animals
The mouse in Tom and Jerry looks nothing like the real mouse, and so at times the reality bites, when kids encounter the real and not very fancy looking mouse. The kind of love and care a kids can have for their pets they might not be able to have for some random animal. But once the kid gets into the habit of loving pets it easier for them to love animals over all.
